To all whom it may concern Be it knownpthat I, EnMoNoDiTAINT, engineer, 19 Passage du Montenegrm' Paris,

citizen of the French Republic, residing at Paris, 19 Passagedu Montenegrmhave inventednew and useful Improvements in Apcable upon which are strung a number t following; is a specification. y

This invention relates to an. apparatus for raising hqulds formed with an endless thin discs alternating with other discs of smaller diameter, such discs being made of any suitable material. The whole is pulled up by a grooved-pulley without any middle part. While passing through the liquid.

the intervals comprised between the discs are iilledwith liquid which isheld back by the superficial tension due tov a suitable ratio between the surface 01 the urge discs and the distance which separates them. 'The liquid raised as far up asthe grooved pulley is poured out in the centre by gravityor centrifugal force according to the speed,owing to the verticalposition assumed at this moment by the discs between which it was held up to that time. i

The accompanying: drawings show diarrammatically and by way of example modes of carrying the invention into prac tical eflect. Fig. 1 1s a v ew in vertical section showng the improvedliquid elevating: device in operative position. I

@When the discs become -,i ertical the water pulley 6+6, the flexion of the cable causes the loweredgesj of the discs to get'nearer Fig. 3 1s a broken elevat on showing a.

It This sliding motion is avoided eitherby providing: small india rubber. discs which yieldas they pass over thepulley, or in the mannershown in Fig. 4; where eachIdisc 1 is replaced by a pairofdiscs 9-'9 placed against one anotherjon'e of these discs9 has V anlouter edgelwherein thethickness of the other slocatedi in such a manner that the discs remain concentric; each dlSG has :lllS.

ing pair while passing: over the pu'lley 6 -6,

the shells 10-10 "bf the i,two "discs under consideration roll one over the other with v out the pair of discs sliding along the cable. The bend of the cable on its passage over the pulley occurs inside the shells.

In the construction shown in Figs. 3 to 14, the shifting of the discs on the cable as it passes over the pulley is avoided by making use of india rubber discs or wings which are either independent or formed integrally with a tube of similar material within which the endless cable passes, or if necessary a certain number of .small discs 2 can be'replaced by ball jointed discs the number of which may vary according tow the sizeof the apparatus and toy its use.

The ball jointed discs may be formed of two pieces 11,.11 '(F or of a concave and convex part or of three pieces 12 12 (Fig. 6), the two pieces or parts being concave and the piece 12 being convex.

These ball jointed pieces allow for the flexion of the whole concern without any pushing occurring against the cable tastener.

In Figs/Z and 8 the apparatus is composed of a tube 13 of india rubber or. other similar material provided with wings. 14; -A metallic cable 3 passes inside this tube 18 to allow the apparatus to withstand traction.

For shafts or pits of great depth or. ator raising apparatus of large diameteigthicker wings 15 than the ordinary wings 14 are provided from place to place. On their passing over the upper pulley these wings, 1 5 carry the weight of the liquid raising-apparatus and thus prevent deformation by crushing of the wings 1d. i

In Figs. 9 and 10 metallic discs .16 arearranged from place to place between each two successive thin discs 1 andhave the same diameter as the latter, such discs bci ng provided with four solid bosses or hollow shells 17-17 fitted at the ends of two perpendicular ,diameters1+1, 11-111, two bosses-or shells being placed on the same-diameter project. upon one of the faces of the disc 16, and the two other bosses or shells project upon the opposite face. These discs 16 the distance between each vary accordingto the amount of fieXion required for the cable .form a .Cardan or universal joint-the .aXes of whose pivots are perpendicular .one to the other and placed in a plane which is perpend i cuilar to the axis of the cable.

In the arrangement shown in Fig..11,,the flexible cable 3. has a squarecross .sectionand all the discs 16 are centrally perforated and have two solid bosses projecting upon the s me d sc a ea square shape and the successive ,discs bear ione npon the other with. their bosses .or shells, the ,axes on which two following idiscs rive e rerpen iwlar O e-rte h th r- Discs with twoizbosses may likewise be resented pen e fl ible eabl rtng a cir- These perforations have 7 cular cross section; it is sulticient for such a purpose to cut out of the central holes of the discs 16 as they are being made a small tongue 18 and a notch 19 (Figs. 12 and 12 The individual rotation of such disc about the cable is prevented by the insertion in the notch '19 of a disc of the adjoining tongue piecel S raised for this purpose paralcludinga cable, and discs arranged in superimposed relation thereon, said discs'including comparatively thin discs spaced apart by thicker discs of materially less diameter, the, relative diameters and, thicknesses of the respective discs being such as to produce a superficial tension to, retain liquid between successivethin discs.

1 2.- An apparatus for raising liquids, in cluding a cable, and discs arranged in superimposed relation thereon, said discs including comparativelythin-discs spaced apart by thicker discs of materially less. diameter, the relative diameters and thicknesses of the respective discs being such as to produce a superficial tension to retain liquid between successive thin discs, and a pulley over which saidca-ble is adapted to pass to permit the discharge of'water from betweenthe disc-s as said :discs approach a vertical plane.

3. An apparatus for raising liquids, comprising an endless cable, thindiscsarranged thereon and thicker discs of less diameter than the thin discs interposed .between said thin discs, said thicker discs being arranged to permit a movement of the cable to .ar range the discs in dis-charge relation without permitting relative movement of said discs on said cable.
